Naturally occurring pollutants within geological formations and contamination of the subsurface. This covers geological contamination — radon from bedrock, heavy metals in rock formations, contaminated groundwater source zones.
Scope
- Radon mapping: Natural radon emission from geological formations
- Heavy metals in bedrock: Naturally elevated arsenic, lead, or cadmium in geological units
- Contaminated land registry: Sites where subsurface is contaminated (industrial legacy, landfills)
- Source zone characterisation: DNAPL plumes, contaminant migration in fractured rock
